Application filed June 26, 1922. Serial No. 570,995.

To aZZ whom it may concern:

Be it known that we, LOUIS B. GOLDBERG, JACOB M. GOLDBERG, NATHAN GOLDBERG, and IL-LIAM GOLDBERG, citizens of the United States, and residents of the city and county of Denver, State of Colorado, have invented certain new and useful Improvements in Portable Liquid-Fuel Camp Stoves; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

The object of this invention is to provide a portable camp stove having means for burning liquid fuel, wherein all the parts of the stove and its equipment may be compactly disposed within or upon the stove casing when the same is not in use.

Briefly the invention comprises a casing within which liquid fuel .burners mounted, one-of whichis controlled by collapsible valve operating 'means adapted to be withdrawn from or returned into the casing. A liquid fuel tankfrom which there projects laterally a vaporizing tube,

is mounted within a protector which is adapted to be retained upon a wall of the casing when not in use with the vaporizing tube projecting into the casing. When in use the protector is removed and the tube passed through an' opening in the casing to place the same across a burner and in operative connection therewith. Conveniently the'retaining means for the protector may be the legs of th stove. The stove also comprises a wind shield and grate adapted to be set upon the'top of the stove for use, the gratebeing removable for packing but so retained on the shield when in use as to prevent spreading of the shield. The grate'is adapted to be folded within the shield and to be placed with the shield be tween the burners and the cover of thecasing for transportation.

tank and'vaporizing tube in operative posiupper edges of whose walls are preferably rolled around a reinforcing rod 11, said casing having a cover or lid 12 hinged there- The stove comprises a main casing 10 the" to at the back, rod 11 serving as a pintle' v vided at the back of the casing upon which.

a grid 15' is swingingly mounted, lugs 16 being struck up from the casing walls to support the forward portion of the grid. The grid *15 is apertured at 17 to accommodate the burner grates 21 and may be apertured elsewhere as shown if desired, while the bottom of the casing is apertured at 18 for draft." The burner cups B which carry spreader plates 19 in any desired manner areconnected by means of a manifold 20 and support the grates 21. :The manifold 20 is provided with "a fuel intake 22 which opens laterallydirectly above a priming cup 0 carried'by one 'ofthe burners, said manifold also being provided withan air. inlet 23 controlled by a damper 24 and rod 25 as disclosed in our copending application Serial No. 509,396, filedOctober 21, 1921', for regulating bothburners'. The opposite burner B is independently controlled at a port 26 governed by a rotary valve 28.hav-

. ing an aperture to register with port 26 and slotted at 29 to receive the end of a screw 30(Fig.1). whichis threaded h g a boss 31 on. he 91119 as disclosed. 111

copending application Serial No. 526,670, filed January 3, 1922. Valve 28 receives in its outer end a hollow reciprocating sleeve 32 operable by a knob 33, and a pin 34 secured in the outer end of said valve 28 passes through slots 35 in the sleeve 32, an expansion spring 36 being disposed about said pin and having its ends friotionally engaging the inner walls of the sleeve. In this manner, the sleeve 32 will be held by the spring 36 in any position of adjustment, either extended for operation of the valve or innermost position within the confinesv of the casing for transportation, the knob 83 workin in Jerture 37 in the casin The casing is supported upon legs each of which has a cross bar 40 adapted to engage the end of the casing when in inoperative position and to engage the bottom of the casin when in operative position, this cross bar being connected with offset pivoting fingers 41 by means of angular portions 12 which engage the sides of the casing when folded up and the tips of which rest on the ground when in use. The pivoting fingers ll are passed through the sides of the casing adjacent the corners which readily permits the legs to fold up at the ends or to swing down under the casing as seen in Fig; 8. This construction is described and claimed in our copending application Serial No. 517,903, filed November 26, 1921. In the present construction these legs perform the additional function when the stove is packed of retaining upon the casing 10 a liquid fuel tank 4 1 and its protector or retainer '50, as seen in Figs. 1, 3 and 5. i

The fuel tank 14 has a rigid extension 45 leading therefrom which carries a laterally disposed vaporizing tube {t6 controlled by a needle valve 47 leading to its tip, and the tube 46 when in use projects through an opening 48 in the end of the casing opposite from knob 33 and overlies the adjacent burner B and cup C and projects into the fuel intake 22. At all times exceptwhen filling, the tank 4-1 will be carried in a pro te-ctor or retainer 50 having one flat wall 51 which is provided with a slot extending inward a short'distance from its end as indicated at 52. This slot 52 receives the tube 16 so that the valve 47 may also be housed in the protector 50 and shielded from damage either during use or during transportati'on; If desiredthe valve 47 may be'withdrawn siifiiciently for more ready manipulation.

When the stove is to be packed the vaporizing tube will be withdrawn from the aperture 18 and the protector placed against the back wall of the casing '10 as seen in the perspective view of Fig. 3 in which instance the tube 46 will'be passed through anop'ening '54 'inthe said"'back wall sothat said tube will he transversely of and" Within the the protector and overlie the same as seen in Figs. 3 and 5. Thus, the legs 10, 12 when in folded position will securely retain the protector and the tank 1 1 in position on the back of the casing so that the same may be carried and the tube 16 will also be protected.

The stove is also provided with a windshield and removable grate. The windshield comprises aback wall to which are hinged end walls 61 at 62. Offset lugs 6 1 are provided on'the end walls 61 by striking up some of the metal, thus providing pockets for ofiset fingers 65 on the ends "of rods 66 rotatably mounted in beads (37 upon the edges of the grate68. A series of these lugs is providedso that the grate maybe Set at various heights, for different purposes of cooking, broilihg, toasting or merely warming; 'In any event the'grate will be positioned a little below the top of the shield so that the upper portions thereof will form retaining walls to prevent any object from i being pushed off the endsor rear of the grate as by another vessel. hen in use, the'windshield rests uponthe grid 15, and thepositioning of the fingers 65 behind the lugs G l. prevents the shield from spreading. lVhen the grate is removed, the fingers may be rotated to lie in'the' plane of the grate. The grate may then be laid on the back wall 60, the end walls '61folded thereover, and

the whole placed" in the top of the stove on i the grid 15, the cover then being closed to retain the parts as seen in Fig. 10, and in. Fig; 11;

' Thus, since the burners are secured pernianently in the casing, the whole stbv'einay be packed up in compact form, with the windshield and grate within the casing, the vaporizing tube'projecting thereint-o from the back, and the tank retainer and proteot-orsecured against the back wall of the casing when. the legs 40 are folded up into packed position, so that the wholeforms a neat, compact unit'without any loose-"parts. To set the stove up, it is merely necessa-rytoswing the legs lO into supporting position, thereby releasing the retainer 50, withdraw the vaporizing tube from opening 54 and insert itfinto aperture 48 and'fuel' intake 22, and setup the" windshield "and grate on If desired the back wall 60 of the windshield may have a flap 70 hinged to "the upper'edge' th'ereof as at 7 2; this flap being slightly longerftlian the backfwall '60 asseen in Figs. 6, "r'sandrfl'o so thatwheir it is moved inthei direction" of the arrow ofFigf 6* a fter thergridfro has been lowered into position. its'ends Will" rest upon the end walls 610i the windshield and be supported thereby. The flap has two functions, one of which isto serve as an additional wind guard and prevent the wind from blowing down onto the burners from above, and the other of which is to serve as acooking. or warming surface. F or, instance flapjacks may be baked thereon. However, said flap 70'may be omitted, as will be seen from Fig. 8. I
